Update status:
There are only these following dump FAILs:

Confirm these FAILs also happen on ARM SVE and they don't fix them.
So, it doesn't make sense we dedicate efforts to fix them.
Just ignore them.
Other than that, we have 2 more FAILs in vect testsuite, these 2 patches will
fix them:
https://gcc.gnu.org/pipermail/gcc-patches/2023-November/635589.html
https://gcc.gnu.org/pipermail/gcc-patches/2023-November/635591.html
After these 2 patches, no dump FAILs need to be fixed, just ignore other dump
FAILs should be reasonable.
Then, we move forward to fix execution FAILs.
